Once the cooling system is sorted (it actually seems to operate reasonably well at the moment) I figure the next stage is the Auto.
Now I realise everyone is aiming for the best possible performance from their cooling system, but I guess my question is that if i was to simply replacing the stock transmission cooler with something a bit more substantial (like a Flex-a-Lite from summit racing), and bypassing the heat exchanger. Could I be confident enough that the auto isnt going to cook on me? Or is it really a matter of having to go the whole hog to even attempt something like the Simpson?
Cheers folks, keep up the great work!

What I have learnt.
Do not run through the radiator.
Fit a temp sender in the pan. 1/8 Bspt or metric equivalent. Must know what temp the oil is going in to the transmission.
Transmission oil cooler the size of the opening in front of the radiator I think its 10" high and half the width of the radiator.
Replace the axillary fan with a10" or 11" ? spal at more than twice the flow.
Make shaw the engine driven fan is working, mine is the only thing you hear when at operating temp and highish rev. a bit annoying but it's flowing some air. removing the mechanical fan is an option BUT if you can't get more than 90 amp alternator then I would not be tackling the Simpson.
The 11" spal Extreme will draw up to 25+ amp. were are the amps coming from and thats only a 11".
I will stay with a mechanical so as to take load of the alternator.
It amazes me how people think they can get air flow through a crowded radiator at no cost.
Your max air flow has to be at 0 KPH, you can not rely on road speed to get your air.
I have not work out if a pusher fan to help the puller spal can be fitted in front of the cooler but that would get some air moving through the drivers side of the radiator.
Air flow costs HP either through a pulley driven alternator or a pulley driven fan.
